Allows you to play your JAMMA games in a cabinet wired according to the Sega System 8 pinout class used by System 1 and System 2 Sega hardware. This 8-bit hardware platform predates System 16 and was used from about 1983 to 1987 not only by Sega but also other manufacturers such as CoreLand and Vic Tokai. See list below.
Please confirm the pinout in the table below matches the wiring of your cabinet. This is especially important for cabinets that have less than 3 buttons and only one coin switch.
This adapter connects to the cabinet according to the following pinout scheme:
|SOLDER SIDE||PARTS SIDE|
(Adapter edge connector facing away, list is ordered right to left)
Important: This adapter does not support the -5V power rail which is not present in these cabinets. Games that require -5V may not run.
Button and Switch Layout:
In most circumstances this adapter will work as intended with your cabinet without any modifications. Problems may occur playing some JAMMA games in a modified cabinet with less than 3 buttons, or only one coin switch present.
If the button order is wrong you may need to swap the wires going to the buttons behind the control panel. If a button doesn’t register at all, say only JAMMA button 2 and 3 work, you may need to run a jumper from button 3 to button 1 at the cabinet wire harness edge connector.
If game can’t be coined up, say in a case where only COIN2 switch is wired in the cabinet, and the game only supports the COIN1 switch, you may need to swap the coin wires on the harness or potentially jumper them together to get the game to coin up.
